Hauler Hero provides an AI-enabled, all-in-one software platform that streamlines CRM, billing, routing, and fleet visibility for waste management companies and municipalities.
SENIOR FRONTEND ENGINEER (CONTRACTOR) Location: Remote — Eastern Europe Engagement: Contractor Experience: Senior, 5+ years Time zone: Must consistently overlap with U.S. working hours ABOUT HAULER HERO Hauler Hero builds the operating system for residential and commercial waste haulers, including dispatch, routing, billing, payments, customer management, reporting, and the driver app that ties field operations together. Our customers are private hauler owners, operators, and municipal waste leaders running essential services every day. Many are still managing their businesses through paper tickets, whiteboards, spreadsheets, disconnected systems, and legacy software. The result is missed revenue, messy routes, limited visibility, and too much time spent fighting fires instead of growing the business. Today, we serve 240+ haulers across the country and are scaling quickly. We are a well-funded, fast-moving vertical SaaS company bringing modern software to an essential industry where the customer need is clear and the opportunity is large. ROLE SUMMARY We are hiring a Senior Frontend Engineer to be a core individual contributor on our web application.

You will work closely with Product, Design, and Backend Engineering to ship features quickly while maintaining a high bar for quality, performance, and usability. This role requires strong ownership, clear communication, and the ability to operate independently in a remote environment.

What this means in practice: - Daily use of tools such as Claude, Claude Code, Cursor, and GitHub Copilot - AI-assisted implementation, refactoring, test generation, and boilerplate - You focus on architecture, UX decisions, edge cases, and quality - You review all AI-generated output with a trust-but-verify mindset This role is not a fit for engineers who are resistant to AI-assisted development or who rely on AI output without understanding the code being produced.
